Bond-Stretch Isomerism: Trapped Isomeric Structures of Hexacoordinate Copper(II) Bispidine Chromophores along a Jahn-Teller Active Vibrational Coordinate

The long and the short of it: Copper(II) complexes of the pentadentate bispidine ligands exist in two isomeric forms (see structure) with bond‐length differences up to 0.5 Å. The stabilization of either isomer may be achieved by a variation of the substituent at N7.
